Summary: Updated kernel packages that fix multiple security issues and several bugs are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - noarch, x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, noarch, ppc64, s390x, x86_64 Red Hat Enterprise Linux Server Optional (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, noarch, x86_64 Red Hat Enterprise Linux Workstation Optional (v. 6) - i386, x86_64 3. Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. * A flaw was found in the way the get_rx_bufs() function in the vhost_net implementation in the Linux kernel handled error conditions reported by the vhost_get_vq_desc() function. A privileged guest user could use this flaw to crash the host. (CVE-2014-0055, Important) * A flaw was found in the way the Linux kernel processed an authenticated COOKIE_ECHO chunk during the initialization of an SCTP connection. A remote attacker could use this flaw to crash the system by initiating a specially crafted SCTP handshake in order to trigger a NULL pointer dereference on the system. (CVE-2014-0101, Important) * A flaw was found in the way the Linux kernel's CIFS implementation handled uncached write operations with specially crafted iovec structures. An unprivileged local user with access to a CIFS share could use this flaw to crash the system, leak kernel memory, or, potentially, escalate their privileges on the system. Note: the default cache settings for CIFS mounts on Red Hat Enterprise Linux 6 prohibit a successful exploitation of this issue. (CVE-2014-0069, Moderate) * A heap-based buffer overflow flaw was found in the Linux kernel's cdc-wdm driver, used for USB CDC WCM device management. An attacker with physical access to a system could use this flaw to cause a denial of service or, potentially, escalate their privileges. (CVE-2013-1860, Low) Red Hat would like to thank Nokia Siemens Networks for reporting CVE-2014-0101, and Al Viro for reporting CVE-2014-0069. This update also fixes several bugs. Documentation for these changes will be available shortly from the Technical Notes document linked to in the References section. All kernel users are advised to upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect. 4. Solution: Before applying this update, make sure all previously released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258 To install kernel packages manually, use "rpm -ivh [package]". Do not use "rpm -Uvh" as that will remove the running kernel binaries from your system. You may use "rpm -e" to remove old kernels after determining that the new kernel functions properly on your system. 5. Bugs fixed (https://bugzilla.redhat.com/): 921970 - CVE-2013-1860 kernel: usb: cdc-wdm buffer overflow triggered by device 1062577 - CVE-2014-0055 kernel: vhost-net: insufficient handling of error conditions in get_rx_bufs() 1064253 - CVE-2014-0069 kernel: cifs: incorrect handling of bogus user pointers during uncached writes 1070705 - CVE-2014-0101 kernel: net: sctp: null pointer dereference when processing authenticated cookie_echo chunk 6.
